使用Python发送邮件

###定义SMTP服和器信息###

# 单个不需要使用列表
to_addr = ["270142877@qq.com", "yan.yu@gogen.com.cn"]

# 定义邮件的内容，类型（类型可以是plain or html等）和字符编码

# 定义发件人的姓名，需要要进行格式化操作
msg["From"] = formataddr(["余雁", from_addr])

# 如果收件人只有1个的话可以定义发件的姓名，如果发件人较多又想实现显示姓名的话，可以对发件人进行循环来实现群发
#msg["To"] = formataddr(["小王", to_addr])

# 对列表转换成字符串，每个元素用逗号分隔
msg["To"] = ",".join(to_addr)

# 定义邮件的主题
msg["Subject"] = Header("Python测试邮件", "utf-8")

# No SSL
#server = smtplib.SMTP(smtp_server, 25)

# Use SSL
server = smtplib.SMTP_SSL(smtp_server, 465)

# 发送的日志输出
#server.set_debuglevel(1)

# 登录到SMTP
server.login(from_addr, password)

# 发送邮件
